DY> (Experiencing a "DUH!" moment.)  Yes, of course. It's zone data so only 
those entities handling zone data need to care.  In my 
still-annoyingly-jet-lagged mind, I made the classic mistake of equating 
"registrars" with "DNS hosting operators" because so many registrars are *also* 
DNS hosting providers.

DY> Ah, interesting. Where the proposed HTTP RRtype has behavior similar to the 
CNAME record, my assumption would be that resolver software would need to know 
what to do once it receives the record.  For that reason, wouldn't all the 
resolvers (or at least an extremely high %) need to be upgraded to support the 
new record?

DY> :-)   Good to know!
